Css in pharmacokinetics
http://www.cyto.purdue.edu/cdroms/cyto2/17/pkinet/pkin01.htm Steady-state concentration ( Css) occurs when the amount of a drug being absorbed is the same amount that's being cleared from the body when the drug is given continuously or repeatedly. Steady-state concentration is the time during which the concentration of the drug in the body stays consistent. See more Unfortunately, it's not as easy as counting chocolates in a box; there are many formulas that are used to calculate various pharmacokinetic parameters—and from there, the average steady-state concentration. But a … See more For a drug with a short half-life, steady state is achieved pretty quickly. If you have a drug with a long half-life and a patient who needs to achieve a therapeutic effect fast—for example, a critical care patient … See more Steady-state concentration can fluctuate depending on many factors, such as: 1. Drug clearance 2. Dosing interval 3. Dose See more In studies conducted in special populations, and in studies for assessing drug interactions, you might be required to take any necessary measurements when drug concentrations … See more
